Dear Yeelight support,
The same problem.
Ambilight suddenly stopped working
Lamp regularly worked for about a week. And Ambilight stopped turning on. In the application, everything is available is registered, there is no response on the lamp.
The main light works without problems.
Reset to factory settings. Nothing has changed.
